SELF-CLEANING PUMP-VALVE.

Original application filed May 19, 1919, Serial No. 298,081.

Divided and this application filed July 14, 1919.

Serial No. 310,579.

To all whom it may concern:

Be it known that I, SYDNEY H. GRAF, a citizen of the United States, residing at Humble, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Self Cleaning Pump- Valves, of which the following is a specification.

This invention relates to new and useful improvements in a self cleaning pump valve and constitutes a division of an application for patent on pumps, filed by me in the United States Patent Oflice on May 19,1919, under Serial Number 298,081.

One object of the invention is to provide a valve of the character described which is designed to be used in a pump used in pumping wells, particularly oil wells, and which is so constructed that it will be actuated by the fluid being pumped to automatically clean itself of sand which is carried up by said fluid and which has a tendency to settle around the valve and clog the same.

Another object of the invention is to provide a valve of this character which is simple in construction, may be cheaply and easily manufactured, and which is very eifective for the purpose intended.

With the above and other objects in view, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawing, wherein:

The figure is a vertical sectional view of the valve.

Referring now more particularly to the drawing the numeral 9 refers to the working barrel, whose upper end carries the valve seat 10, having the central fluid passageway 11. This seat is retained in position by means of the valve cage 12, which is threaded onto the upper end of the working barrel 9, and which clamps sald seat in position. The lower end of the pump rod (not shown) is attached to the cage 12, and through this rod, said working barrel is reciprocated up and down. Within the cage 12, there is a valve 14;, which controls the passageway 11, and this valve has the depending stem 15 extending down through the fluid passage way 11, and the lower end of this stem carries the flared spiraled fin 16. As the fluid passes under pressure through the barrel 9, it operates against the spiraled fin 16, to rotate the same thus rotating the valve 14. A fiat {in like agitator 17 projects upwardly from the valve 14, and as the valve rotates, this agitator prevents the sand with which the fluid is laden, from settling in the cage 12, and interfering with the working of the valve; by said sand being kept in agitation, it is more readily caught up by the fluid passing through the tubing of the pump.

The fluid passing upwardly through the working barrel 9 during the operation of the pump will cause a rotation of the spiraled fin 16, thus rotating the valve 14 and the agitator 17, to prevent the sand from settling in the cage 12, and interfering with the working of the valve therein.

What. I claim is:

1. In a pump, a working barrel, a valve seat having a fluid passageway, a valve controlling said passageway, a stem fixed to the valve and extending down through said passageway, whose lower end is formed into a spiraled fin, a cage inclosing the valve and an agitator fixed to the valve within said ea c.

In a pump, a valve seat having a fluid passageway therethrough, a valve cage attached to said seat, a valve within the cage, an agitator carried by the Valve within the cage and means actuated by the fluid passing through the pump and partially rotating the 1ylalve and agitator with each impulse of the uid.

3. In a pump, a valve seat having a fluid passageway therethrough, a valve controlling said passageway, an agitator, carried by the valve, a cage inclosing the valve and agitator, and a spiraled fin depending from the valve, and actuated by the fluid passing through the pump to rotate the valve and agitator.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

SYDNEY H. GRAF.
